WAR PROTECTING DEVICE Filed May 8. 1936 2 Sheets-Sheet 2 lNVENTbR Sol/re): bazarg zdn v BY ATTORNEY Patented Apr. 20, 1937 UNITED STATES PATENT caries 4 Claims.

This invention relates to new and useful im. provements in a war protecting device.

The invention has for an object the provision of a substantially horizontal wheel to act as a shield and adapted to be rotated to centrifugally throw bombs and other explosives dropped on articles and devices being protected. For ex ample, several of the protecting devices may be mounted upon a ship and protect the ship from aerial bombs. I

Still further the invention contemplates the provision of a spiral hub upon the wheel device arranged ina manner so as to be capable of quickly dispersing poisonous gases.

Still further the invention proposes the adaption of the war protecting device to underground forts andother strategic positions.

fitlll further the invention proposes the provision of a revolvable closure element in the top of a chamber or underground passage and having a small entrance door associated in a novel manner with a stationary member extending over one side thereof and having a door alignable with said door.

Furthermore, theinvention contemplates the association of a substantially horizontal wheel acting as a shield and superimposed on said closure.

.For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In Fig. 1 a ship III is shown provided with several war protecting devices ll. Each of these devices includes a substantially horizontal wheel Il acting as a shield. Means are associated with the wheel for turning the wheel to centrifugally throw bombs and other explosives dropped thereon- The wheel ll comprises a rim portion supported by a plurality of adjacent fan shaped spokes 12 which in turn are connected with a hub portion I3. This hub portion comprises a spiral section l3 and a plurality of radial reinforcement members l3 A vertical shaft laconnects with the hub.portion of the wheel and is.

supported in the vertical portion by a pedestal l5. horizontal position on the vertical shaft l4 and the wheel H In operation the war protecting devices prevent bombs and other explosives from being dropped upon the object or device being protected. The Wheels ll have a sufliicient span so asto substantially cover the entire object being protected. The rotations of the Wheels prevent bombs and other explosives which are dropped from reaching the protected object. When they strike the wheels they will be thrown by centrifugal force outwards. Furthermore, the spiral hubs l3 of the wheels and the fan shaped spokes l2 are very eflicient in dispersing poisonous gases.

In Figs..3-8 inclusive a modification of the invention has been disclosed wherein an underground passage or the lower compartment of a ship is protected thereby. More specifically, in this form of the invention there is a substantially horizontal wheel 2! which is supported at its center by a vertical shaft 22. This vertical shaft extends downwards through a revolvable closure member 23. This closure member is arranged in the top of the underground compartment or passage 24. A stationary member 25 extends over one side of the revolvable closure element 23 and is attached to a stationary object such as the ground 26.

The wheel 2i has-a plurality of fan shaped spokes 21 by which it' is connected to a spiral hub portion 28. The vertical shaft 22 is supported by a standard construction 29 which is mounted on the stationary member 25. The revolvable closure element 23 has several rollers 30 mounted on its bottom which ride upon a supporting shoulder 3| built into the ground. This revolvable member 23 is also arranged coaxial upon the shaft 22 and is supported by a flange 32. At the bottom the shaft 22 is provided with a gear 33 which meshes with a pinion 34 of a driving mechanism 35. This driving mechanism is mounted on the floor of the compartment or passage 24.

A plurality of supporting brace arms 36 are mounted in the ground and extend upwards. At their top ends these support arms 36 are provided with rollers 31 rotatable in spring bearing's 31'. The rollers are engaged by circular flanges 38 on the periphery of the ring 21'.

The extension ring 2 l is spaced by washers 2| from wheel 2! and is concentric with the Several arms I6 hold the wheel ll in a latter. Rivets 2| secure members 2|, 2| and 2 I- together.

Auxiliary arms 39 are movably attached by hinges 39 at their top ends with the periphery of the ring 2| An expansion device 39 in the form of a turn buckle construction is connected between each of the auxiliary'arms 39 and the ring 2| to hold the arms in various predetermined fixed angular'positions. At the lower ends the arms 39 connect with segments 39, which when taken together as a unit form an annular member encircling the arms 36. This annular member forms a rotating or moving obstruction to an attacking enemy.

The stationary member 25 is provided with a door 4|! which is alignable with a door 4| mounted in a small entrance opening in the closure element 23. This door 4! is pivotally supported by a pintle 42 and has a lock 43. This lock has a bolt 44 extending from both ends. The end 44* is adapted to engage in keeper 45 which holds the door 4| locked. The end 44* extends into a recess 46 in the door and engages a control slide 41. This control slide is resiliently urged upwards by a spring 48. It is formed with an opening 49 which when aligned with the rear end 44 of the bolt permits the lock to be opened. The upper end of the slide plate 41 is provided with several teeth 49' adapted to mesh with complementary key teeth 49 on the material of 'the stationary member 25 adjacent the door 40. The upper end of the plate 41 slightly projects above the top face of the element 23. The stationary member 25 has a recessed portion 25- through which the upper end portions 49' of the plate 41 may pass when the element 23 turns. A removableladder 50 is provided for climbing up through the doors when they are aligned.

The operation of the device is as fol1ows:-The driving element 35 rotates the shaft 22 which in turn rotates the closure element 23 and the Wheel 2M which are mounted on the shaft 22. When the device is thus operating an enemy cannot drop bombs or other missiles upon the closure element 23, and furthermore, enemies on the ground cannot gain entrance through the device because of the rotating closure element 23. If they jump on this rotating element with the view of prying the door 4| open they will be hurt by being forced against the stationary element 25. If they open the door 40 of the stationary element 25 they cannot gain access through the door 4|, and so cannot enter the underground passage.

In order to open the door 4| it is necessary that the driving device 35 be brought to a stop at a position in which the doors 40 and 4| are aligned. In this position, and only in this position, do the key teeth 49 mesh with the teeth 49 to press down the plate 4'! against the action of the spring 48. Then the bolt 44 may be moved towards the left so that it disengages the keeper 45. The door 4| may now swing open.

The revolvable closurearrangement illustrated in Figs, 3 to 5 may also be used on ships, on top of forts, buildings, etc.

' While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclose-d and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
